Overview
Affected versions of this package are vulnerable to Improper Removal of Sensitive Information Before Storage or Transfer via the uefi_vars_write function. The UEFI_VARS_REG_PIO_BUFFER_TRANSFER register is not cleared between write callbacks with uefi_vars_write and read callbacks with uefi_vars_read, so a malicious guest can read residual memory from previous invocations.
